HydroShield Potomac is owned by Patrick Cook. Patrick Cook left Kailua Hawaii 30 years ago and began his life on the east coast. He met his wife Heather and they have been married happily since 1988.  They settled in Laytonsville, MD and there they raised their two children. Patrick and Heather began their entrepreneurial journeys shortly there after. Patrick started an automotive restoration business and Heather, after graduating with her BS in interior design, began her design business (Inside Design). Heather is a known and respected interior designer in the D.C. Metropolitan area and has been serving the area for 25 years. Patrick has maintained great relationships with all those he has had the privilege to serve over the years.

They have¬†¬†lived by, and have, a life-long reputation for operating under the same business philosophy:¬†¬†Provide your customers with the highest level of service and quality of products that can best serve¬†their¬†needs, and stand behind them! Over the years of working and living this way, they haven’t established a large customer base, rather they have a large network of friendships.¬†

In 2012 Patrick decided to leave the automotive industry, wanting to utilize his restoration skills and work in conjunction with his wife. During this time they decided to renovate a small, turn-of-the-century cottage near Annapolis.

As an investment property, they wanted to product their glass and stone surfaces with the best possible products. After extensive research and conversations with builders, Patrick was not satisfied with the options available until he came across HydroShield. So impressed with HydroShields products, technology, business integrity and philosophy he became a HydroShield certified dealer.
